• Message number: 821

• Message text: Une incohérence a été constatée (assignation des valeurs)

Quelle est la cause de ce problème?

You want to change the value assigned to a characteristic. However, the
change causes inconsistency, so the new value is not allowed.
The inconsistency may be for the following reasons:
A precondition or selection condition is violated.
The characteristic is a single-value characteristic, and different
values have been set by constraints, actions, or procedures.
In classification, inconsistencies occur when you change the value set
of a characteristic if objects or classes have already been classified
with values from the previous value set (for example, in the case of a
configurable material or a generic material).
